Before we go into a comprehensive comparison, here is a brief synopsis of how the 40D grades versus the 550D with respect to portability, imaging, features and an overall rating.

Following is a preview of the gallery photos for Canon EOS 40D and Canon EOS 550D. The whole galleries are viewable at Canon 40D Gallery and Canon 550D Gallery.

Oftentimes, it is hard to envision the difference between sensor sizing just by reviewing specs. The photograph here should offer you a much better sense of the sensor measurements in the 40D and 550D.

All in all, each of the cameras feature the identical sensor size albeit not the same resolution. You should count on the Canon 550D to offer you extra detail using its extra 8 Megapixels. Higher resolution will also make it easier to crop shots way more aggressively. The older 40D is going to be disadvantaged with regard to sensor tech.
